Woman killed by Phoenix-area police had popular online video

MESA, Ariz. – A woman shot and killed by Phoenix-area police after they say she charged them with a knife had posted a popular online video last year in which her dog tries to comfort her as she cries.

Police in the Phoenix suburb of Mesa say several officers went to 24-year-old Danielle Jacobs' home Thursday in response to calls about a suicidal person. Authorities say two officers shot the woman when she lunged toward them with a knife.

Her 2015 video shows Jacobs sobbing and striking herself while her dog tries to comfort her. Her description of the video said it showed what it's like to have Asperger's syndrome.

People with the autism spectrum disorder can be highly intelligent and have narrow, sometimes obsessive, interests but lack social skills.
